[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 2 and Figure 4 As shown in the figure, an embodiment provided by the present invention: a cloth guiding roller assembly with adjustable tension, including a bottom plate 1. A plurality of double-acting cylinders 4 are fixedly connected to the top of the bottom plate 1. Both output ends of the double-acting cylinders 4 are fixedly connected with first connecting blocks 5. A plurality of first connecting bars 7 are fixedly connected to the outer walls of the first connecting blocks 5 on one side. A plurality of second connecting bars 9 are fixedly connected to the outer walls of the first connecting blocks 5 on the other side.

The outer walls of the third connecting bars 11 are all slidably connected with second connecting blocks 12. Both ends of the third connecting bars 11 are slidably connected with second connecting rods 10. The inner walls of the second connecting rods 10 are all slidably connected to the outer walls of the second connecting bars 9. First supporting blocks 13 are fixedly connected to the tops of the second connecting blocks 12. A first cloth guiding roller body 14 is fixedly connected between the two first supporting blocks 13. A plurality of fixed plates 2 are slidably connected to the outer wall of the first cloth guiding roller body 14. A limiting assembly is arranged on the top of the bottom plate 1. The limiting assembly is used to limit the cloth during the winding process. The limiting assembly includes a connecting plate 20. The bottom of the connecting plate 20 is arranged on the top of the bottom plate 1. A plurality of first chutes 3 are arranged inside the bottom plate 1. The bottoms of the first connecting blocks 5 are all fixedly connected with first sliders 6. The outer walls of the first sliders 6 are slidably connected to the inner walls of the first chutes 3. The bottoms of the fixed plates 2 are fixedly connected to the top of the bottom plate 1.

[0033] Specifically, in the tension adjustment process of the fabric guiding roller assembly, first start the double-acting cylinder 4. After the double-acting cylinder 4 is started, it drives the first connecting block 5 to move in opposite directions by means of the output ends on both sides. During this movement process, the movement of the first connecting block 5 drives the first slider 6 to slide on the inner wall of the first chute 3. The first slider 6 can reduce the friction generated when the first connecting block 5 moves. During the movement process of the first connecting blocks 5 on both sides, they respectively drive the second connecting bar 9 and the first connecting bar 7 to move synchronously and unfold. During the movement of the second connecting bar 9 and the first connecting bar 7, they respectively drive the second connecting rod 10 and the first connecting rod 8 to perform rotational movements. By means of the rotational actions of the second connecting rod 10 and the first connecting rod 8, the second connecting block 12 is driven to move in the up and down directions through the third connecting bar 11. When the second connecting block 12 moves up and down, it drives the first fabric guiding roller body 14 to move synchronously in the up and down directions through the first support block 13. At the same time, by using the groove provided inside the fixed plate 2, the movement of the first fabric guiding roller body 14 can be limited. Through the up and down movement of the first fabric guiding roller body 14, the tension of the fabric on its surface is adjusted, and finally the goal of targeted tension adjustment according to the characteristics of different fabrics is achieved, improving the efficiency of the equipment's tension adjustment and enhancing the practicality of the equipment.

[0034] Refer to Figure 1 and Figure 3 , a second support block 15 is fixedly connected to the top of the bottom plate 1. A servo motor 16 is fixedly connected inside the second support block 15. The output end of the servo motor 16 is fixedly connected to a second fabric guiding roller body 17. The outer wall of the second fabric guiding roller body 17 is slidably connected inside the fixed plate 2. A third fabric guiding roller body 25 is slidably connected inside the fixed plate 2. A third support block 18 is fixedly connected to the top of the bottom plate 1. An electric telescopic rod 19 is fixedly connected to the inner wall of the third support block 18. The output end of the electric telescopic rod 19 is fixedly connected to a connecting plate 20. Second chutes 24 are respectively opened inside the fixed plate 2. Second sliders 21 are fixedly connected to both sides of the connecting plate 20. The outer walls of the second sliders 21 are slidably connected to the inner walls of the second chutes 24. A plurality of baffles 23 are arranged at the top of the second chutes 24. Fourth connecting bars 22 are fixedly connected to the bottoms of the baffles 23. The outer walls of the fourth connecting bars 22 are slidably connected inside the connecting plate 20.

[0035] Specifically, during the specific use process of the fabric guiding roller assembly, the servo motor 16 is started, and the fabric on the outer wall of the second fabric guiding roller body 17 is driven by the servo motor 16 for winding. At this time, the electric telescopic rod 19 is started, and the connecting plate 20 is driven to move by the powerful driving force of the electric telescopic rod 19. When the connecting plate 20 moves, the second slider 21 slides on the inner wall of the second chute 24. The second slider 21 here can play a role in limiting the movement of the connecting plate 20. During the movement of the connecting plate 20, the baffles 23 on both sides are driven to move in opposite directions on the outer wall of the second fabric guiding roller body 17 through the fourth connecting strip 22. By using such baffles 23, the winding operation of the fabric can be limited, preventing problems such as wrinkles or curling caused by the deviation of the fabric during the winding process, thereby enhancing the quality of the fabric.

The first slider 6 is used to reduce the friction during the movement of the connecting block one 5. During the movement of the connecting block one 5 on both sides, the second connecting strip 9 and the first connecting strip 7 are respectively driven to move synchronously. During the movement of the second connecting strip 9 and the first connecting strip 7, the second connecting rod 10 and the first connecting rod 8 are respectively driven to perform rotational movements. The rotational actions of the second connecting rod 10 and the first connecting rod 8 drive the connecting block two 12 to move up and down through the third connecting strip 11. The up and down movement of the connecting block two 12 drives the first fabric guiding roller body 14 to move synchronously through the first support block 13. The groove inside the fixing plate 2 is used to limit the movement of the first fabric guiding roller body 14. The up and down movement of the first fabric guiding roller body 14 is used to adjust the tension of the fabric on its surface, achieving the purpose of targeted tension adjustment according to different fabric characteristics, improving the equipment tension adjustment efficiency, and enhancing the practicality of the equipment. During the use process of the fabric guiding roller assembly, the fabric on the outer wall of the second fabric guiding roller body 17 is driven for winding by the servo motor 16. At the same time, the electric telescopic rod 19 is started. The connecting plate 20 is driven to move by the electric telescopic rod 19. During the movement of the connecting plate 20, the second slider 21 slides on the inner wall of the second chute 24. The second slider 21 is used to limit the movement of the connecting plate 20. During the movement of the connecting plate 20, the baffles 23 on both sides are driven to move in the opposite direction on the outer wall of the second fabric guiding roller body 17 through the fourth connecting strip 22. The baffles 23 are used to limit the winding of the fabric, preventing problems such as wrinkles or curling caused by deviation, and enhancing the quality of the fabric.
